Es sind elektromagnetische Andrückvorrichtungen für eine Andrückrolle an eine zum Antrieb eines Aufzeichnungsträgers dienende Transportrolle bekannt. There are electromagnetic pressure devices for a pressure roller to drive a Recording medium serving transport roller known.

Bei diesen bekannten Ausführungsformen bilden die jeweiligen Rollenpaare zusammen ein elektromagnetisches System, d. h., zumindest eine Rolle ist selbst als Magnet ausgebildet, und in ihr wird der Erregerstrom über Schleifringe geführt.In these known embodiments, the respective pairs of rollers together form an electromagnetic one System, d. That is, at least one roller itself is designed as a magnet, and the Excitation current passed through slip rings.

Eine solche Ausbildung hat verschiedene erhebliehe Nachteile. Einerseits bedingt sie einen verhältnismäßig komplizierten Aufbau. Zum anderen ist die Stromzuführung störanfällig, und schließlich erfordert die gesamte Vorrichtung eine laufende Überwachung und Wartung.Such a design has several significant disadvantages. On the one hand, it requires you to be proportionate complicated structure. On the other hand, the power supply is prone to failure, and ultimately required the entire device requires ongoing monitoring and maintenance.

Der Erfindung liegt die klare Erkenntnis dieser Verhältnisse und die Aufgabe zugrunde, die angegebenen Mängel zu vermeiden.The invention is based on the clear recognition of these relationships and the object of the specified To avoid defects.

Gemäß der Erfindung ist dies dadurch möglich geworden, daß von dem Rollenpaar eine Rolle aus nicht magnetischem Material besteht und daß deren Welle in den als Joch eines U-förmigen Magneten dienenden Schenkeln gelagert ist.According to the invention, this has become possible in that one role from the pair of rollers non-magnetic material and that its shaft in the yoke of a U-shaped magnet serving legs is mounted.

Dabei können die Stirnenden der Schenkel des U-förmigen Magneten als Polschuhe ausgebildet sein, die die Gegenrolle teilweise umgreifen.The front ends of the legs of the U-shaped magnet can be designed as pole shoes, which partially encompass the counter roller.

Eine besonders zweckmäßige Ausführungsform der Erfindung besteht darin, daß die wiederum als Polschuhe ausgebildeten freien Enden der Schenkel des U-förmigen Magneten magnetisierbare Endscheiben der nicht magnetisierbaren Transportrolle teilweise umgreifen, mit denen sie zusammen das Joch des Magneten bilden.A particularly useful embodiment of the invention is that the turn as Pole shoes formed free ends of the legs of the U-shaped magnet magnetizable end plates partially encompass the non-magnetizable transport roller, with which they together with the Form the yoke of the magnet.

An Hand der Zeichnung ist die Erfindung beispielsweise erläutert.The invention is explained by way of example with the aid of the drawing.

Es zeigen F i g. 1 und 2 sowie F i g. 3 und 4 je zwei Ausführungsformen der Erfindung in Seitenansicht, teilweise geschnitten, und in Stirnansicht.It shows F i g. 1 and 2 as well as F i g. 3 and 4 each two embodiments of the invention in side view, partially cut, and in front view.

Danach ist eine Transportrolle 1 aus nicht magnetisierbarem Material auf einer Antriebswelle 2 gelagert. Diese ist gemäß Fig. 1 und 2 durch die Schenkel 3 eines U-förmigen Elektromagneten 4 geführt, dessen Stirnenden als Polschuhe 5 ausgebildet sind. Letztere umgreifen teilweise eine Andrückrolle 6.Thereafter, a transport roller 1 is made of non-magnetizable Material stored on a drive shaft 2. This is shown in FIGS. 1 and 2 by the Leg 3 of a U-shaped electromagnet 4 out, the front ends of which are designed as pole shoes 5 are. The latter partially encompass a pressure roller 6.

Gemäß F i g. 3 und 4 umgreifen die wiederum als Polschuhe 7 ausgebildeten Stirnenden der Schenkel 3 des U-förmigen Elektromagneten 4 teilweise Endscheiben 8 der Transportrolle 1, die jedoch aus ma-Elektromagnetische Andrückvorrichtung für eine AndrückrolleAccording to FIG. 3 and 4 encompass the ends of the legs 3 of the U-shaped electromagnet 4, which are in turn designed as pole shoes 7, partially end disks 8 of the transport roller 1, which, however, consist of an electromagnetic pressure device for a pressure roller

gnetisierbarem Material bestehen und zusammen mit den Schenkeln 3 das Joch des Magneten 4 bilden.There are gnetisable material and together with the legs 3 form the yoke of the magnet 4.

Aus dieser Darstellung ist ersichtlich, daß die Erregung des Magneten 4 einen Magnetfluß durch die Schenkel 3 bzw. 3, 8 und die Andrückrolle 6 hervorruft. Letztere wird dementsprechend an die Transportrolle 1 angelegt, so daß ein zwischen beide Rollen 1, 6 eingeführter bandförmiger Aufzeichnungsträger 9 sofort und zuverlässig von dem Rollenantrieb mitgenommen wird.From this illustration it can be seen that the excitation of the magnet 4 causes a magnetic flux through the Leg 3 or 3, 8 and the pressure roller 6 causes. The latter is accordingly attached to the transport roller 1 applied so that a tape-shaped recording medium inserted between the two rollers 1, 6 9 is taken away immediately and reliably by the roller drive.

Der Aufbau und die Montage der neuen Vorrichtung sind demgemäß einfach und die Stromzuführung zuverlässig, so daß sich eine Wartung praktischThe construction and assembly of the new device are accordingly simple and the power supply reliable, making maintenance practical
